Hi,
since Freenode is doomed today, i ask the direct way.
Following Filesystem:
Label: 'data' uuid: 3a6fd6d7-5943-4cad-b56f-2e6dcabff453
Total devices 6 FS bytes used 7.02TiB
devid 1 size 1.82TiB used 1.82TiB path /dev/sda3
devid 2 size 2.73TiB used 2.48TiB path /dev/sdc3
devid 3 size 931.38GiB used 931.38GiB path /dev/sdd3
devid 5 size 931.51GiB used 931.51GiB path /dev/sde1
devid 6 size 931.51GiB used 931.51GiB path /dev/sdf1
devid 7 size 2.73TiB used 2.48TiB path /dev/sdb3
Btrfs v3.12-dirty
If I try to mount it from dmesg:

What happened before:
One disk was faulty, I added a new one and removed the old one,
followed by a balance.
So far so good.
Some days after this I accidently removed a SATA Power Connector from
another drive, without noticing it at first. Worked about an hour on
the system, building new Kernel on another Filesystem. Rebooted with my
new Kernel and the FS was not mountable. I noticed the "missing" disk
and reattached the power.
So far i tried:
mount -o recovery
btrfs check
(after google) btrfs-zero-log
Sadly no luck. Whoever I can get my Files with btrfs restore. The
Filesystem contains mainly Mediafiles, so it is not so bad, if they
were lost, but restoring them from backups and sources will need
atleast about a week. (Most of the Files are mirrored on a private
Server, but even with 100MBit this takes a lot of time ; )
Some Idea who to recover this FS?
Kind Regards
Tetja Rediske
